Question about BAN.

Hey guys,
i have a question about BAN on steam/vac or whatever it's called. so will a whole my account get banned, or only that game and i'll still be able to play other games and chat with friends?
if i get banned, will anyone know this, like it's gonna be written somewhere that im banned or not?

dude,stand it!
you are a hacker.i mean if you are ashamed to use hacks then you are wrong on this website.
there is no way to hide that you are banned.
i got banned on MW2 and all my friends saw it and i said: mates, i hacked!
nothing about it.unless all your skill was thanks of the hacks.

hey guys ive got a question too..i got banned by VAC and now i wanna know if i buy a new game where u can create a new steam account,can u play the game mw2 if u installed it before or something like that?
